Dynamic Video Streaming Optimization

IP surveillance systems must manage their video streaming carefully in order to achieve the right balance of video quality and network performance. Moxa’s IP video solution includes versatile video streaming optimization technology that flexibly adapts to the network.

DynaStream™ for System and Network Efficiency

Moxa’s breakthrough DynaStream technology automatically controls the video frame rate based on network conditions, and is automatically included in all VPort series products. Whenever DynaStream detects an event such as a network traffic jam, the system can automatically reduce all of the VPorts’ frame rates to conserve network resources. When DynaStream detects an event such as a DI alarm, it can automatically increase video quality in response by increasing the frame rate. This is done with CGI commands, SNMP, or Modbus/TCP. This new tool is extremely flexible. Not only can it change system resources and network bandwidth so that critical data systems can maintain Quality of Service (QoS), in addition it can guarantee that system performance will not be impacted by video streams.

Multiple Video Streams for Versatile Applications

Different applications, such as live viewing, video recording, and image analysis, may have different video performance requirements. For this reason, Moxa’s VPort products provide multiple video streams, each one customizable for different application requirements.

Moxa provides a distributed network video recording (NVR) solution to decentralize video storage and reduce network bandwidth demands. Instead of transmitting all recorded videos to the control center, the system uses scalable NVR products at field sites for video data storage. With this distributed approach network resources are conserved, since only video data that is actually needed will be transmitted over the network. NVR, SCADA, and Center Management System (CMS) engineers can all benefit by being able to view live video feeds or playback recorded video, while leaving more bandwidth available and improving surveillance efficiency.
